Yes, indeed, there are still quite a few gaps. Which puzzle do you have in mind? I can send you instructions how to download and run the old applet JAR file on your local machine. Feel free to email me and we can discuss further. :)
OK. I can email you instructions how to download that. You will need appletviewer that comes with java8. My email address is on my homepage. Or you can reach me via TPG discord.
